I've used a lot of Cypress on outdoor cabinets and furniture and it is fantastic to work with. It machines great and weathers well. Just be aware that it changes radically with the humidity so you always have to leave room for expansion. If you use it indoors where there is a/c it will shrink way beyond what you think possible. I had a cypress door shrink 3/8" in six months (in width). Contact one of your local cabinet shops and find out where they buy their lumber. If you make friends, they may even allow you to buy through them.
